Influence of thalamic dopamine on primate cortical function as inferred from the density of the dopamine innervation in the thalamus (represented by three different intensities of red) and from the organization of thalamo-cortical connections. The cortical regions receiving input from the most densely dopamine innervated thalamic nuclei are represented in the darkest gray color to indicate the impact of thalamic dopamine on their corresponding functional domains. These regions include the prefrontal and motor cortices and part of the posterior parietal cortex. In contrast, the cortical areas receiving input from the thalamic nuclei with the least dopamine innervation are shown in the lightest gray shade and correspond to the primary visual (VI), auditory (AI), and somatosensory (SI) areas. A, anterior group of nuclei; CL, central lateral nucleus; CM-Pf, centromedian-parafascicular complex; GL, lateral geniculate nucleus; GM, medial geniculate nucleus; LD, lateral dorsal nucleus; LP, lateral posterior nucleus; M, midline group of nuclei; MD, mediodorsal nucleus; Pcn, paracentral nucleus; Pul, pulvinar nuclei; R, reticular nucleus; VA, ventral anterior nucleus; VL, ventral lateral nucleus; VPL, ventral posterior lateral nucleus; VPM, ventral posterior medial nucleus; VPMpc, ventral posterior medial nucleus-parvocellular part.
